Be it known that I, NAPoLnoN ST. PETER, Jr., a citizen of the United States, residing at Fairfield, in the county of Somerset and State the bottom. The ends of this hood are promounted a revoluble shaft 17, which extends of Maine, have invented new and useful .lm-

provements in Stroot-Cleaning Apparatus, of which the following is a speeiii ation.

This invention relates to street-sweepers. The objects of the invention are to improve and simplify the construction of such devices.

With-the foregoing objects in view the invent-ion resides in the particular combination and arrangement of parts and in the precise details of construction hereinafter described and claimed as a practical embodiment thereof. 1

In the accompanying drawings, forming a part of this specification, Figure 1 is a sidc' elevation of the machine.

Fig. 2 is a rear elevation thereof.

Fig. 3 is a section on line 3 3, Fig. 1. Fig. 4 is a section on line 4 4-, Fig. 1. Fig. 5 1s a detail VlGW of one of the sweepin -rolls. Fig. 6 is a perspective view of the re l-adjustinglever and its connections; and Fig. 7 is an enlarged section through the spraying apparatus, the spray being shown in elevation.

Referring to the figures by numerals of reference, 1 is the platform of a motor-propelled vehicle, and arranged on this platform 2, having a perforated dome 3 on the top thereof, which is partitioned from the receptacle by means of gauze 4. A sponge 5 or other like material is arranged within the dome and supported therein by the gauze 4, and this sponge is adapted to be keptmoist, so as to prevent the escape of any dust that may be discharged into the receptacle 2. An outlet 6 is arranged at the center of one side of the receptacle and at the bottom thereof, and the bottom 7 of the receptacle is inclined from the rear and ends thereof down to the outlet 6, and the outlet is normally closed by a door 8. A tank 9 is arranged on a bracket 10 at one end of receptacle 2 and is provided with a pump 11, whereby air may be compressed therein. A pipe 12 extends from the tank into the receptacle 2 and opens into a spray 13, which is supported from the top of the receptacle by hangers let.

A hood 15 is secured to and depends from one end of the platform 1 and is open only at through the center of a cylindrical brush 18. A collar 19 is loosely mounted on each end of the shaft 17 and is secured to one end of a chain 20. These two chains are secured to substantially semicylindrical segments 21, fastened at the ends of a shaft 22, which is mounted in the walls of the hood 15 and has an operating-lever 23. A toothed segment 24 and a spring-pressed pawl 25 are provided for locking the lever in adjusted position. A motor 26 of any suitable form is arranged upon the platform 1 and is adapted to transmit motion to the shaft 22 through a chain 27, which extends over a sprocket 2S, arranged on the shaft17, and a sprocket 29, secured to the shaft 30 of the motor 26. An outlet 31 is formed in the top of the hood 15 and comnnmicates with a fan-casing 32, having an outlet-pipe 33, which opens into the top of the receptacle 2. A rotary fan 34 is mounted within the casing 32 and is driven by the motor 26 through a chain 35, which is mounted on sprockets 86, located on the shaft 36 of fan 32 and on the shaft 30 of the motor 26.

In using the apparatus herein described water is placed in the tank 8, and air is compressed within the tank by means of the pump 1. A valve 37 is arranged within the pipe 12, so as to prevent the compressed air from discharging the water through pipe 12 except when desired. l'Vhen "the vehicle is propelled forward, rotary motion may also be transmitted to the brush 18 from the motor 26. This brush, however, need not be in contact with the ground, but can be dropped into suchposition by swinging levcr 23 so as to unwind the chains 20 from the segments 21. The motor 26 will also rapidly rotate the fan .34, and a suction will be established thereby from the hood 15, and dust, &c., brushed by the roll 18 will be drawn into the casing 32 and discln'u'ged through pipe 33 into receptacle 2. The air forced into the receptacle will escape thrmlgh the aperture-dome 3 but it will be understood that the moist sponge 5 will prevent the dust from passing outward therewith. \Vhcn it is desired to remove the material from the receptacle 2, the valve 37 is opened and water is discharged under pneumsiic pi-cssnie from the tank 9 to the spray 13, from which it is discharged upon the contents of the casing. The door 8 can then be opened, end the dirt, 800., which has accuninlnted within the receptacle can he renmvcdwvithout creating d st It will he seen that the hood 15 extends beyond one side oi the platlcmn this eons inction being shown there pnrticnlz'irlx in it 1 2's. 2 and. 3, and therefore the ln'ush 1% can he brought ('losO m :1 curl) and the gutters ot n-sti'eet cleaned as thoroughly :is the road-bed.

liming thus described the illVtil'ltlOIlfll-"llQt claimed as new is-- in a, sweet-cleaning device, a supporting- {T21R10} :1 hood depending from the frame and 1 i l l l formed with vertical slots and extending at one side beyond the flame, a brush-shaft vertically movable in said slots and having brushes, a second shaft extending through the upper portion of said hood and having segments, chains secured. to said segments and connected with. said. brush-shaft, and a handle-lever fixed to one of the segments for opc'i'sting the shaft, substantially as specified.

In testimony whereof I e'fiix my signature in presence of two Witnesses.
